53 Claims.

The present invention relates to a combination spring draw bar and spring bumper adapted to be secured to a car end with all its parts, with the possible exception vof the car attachment means, exterior of the car frame or body. The spring means is common to both the bumper and draw bar, compression springs being utilized and being subjected to compression by both draft and impact forces. new device may be constituted by castings, or by shapes and bars, or both.

Two practical embodiments of the invention are shown by way of example in the accompanying drawings,

Referring rst to the embodiment shown in Figures 1 to 5, reference numeral I0 designates a cast bracket, housing, or support adapted to extend across a car end to serve as an end sill,

the bracket having integral rearwardly extending arms II and I2 adapted to be secured to the longitudinal car sills or other structural portions.

The bracket has a rectilinearly extending upright rear wall I3 and a horizontal forwardly or outwardly extending bottom wall I4 at right angles to the rear wall. 'Adjacent its ends the bracket has a pair of abutment portions I5 and `II hav'- ing faces I5a,.I5b, IGa and I6b spaced forwardly of the wall I3, faces I5b and I6b being stepped somewhat forwardly of faces I5a and I6a, respectively, all the faces being substantially perpendicular to the wall I4. 'Ihese abutment portions are integral with the wall I4 and have integral web connections I'I and I8 with the ends of wall I3 and merged with the latter adjacent arms II and I2.

. Spaced somewhat inwardly of abutment portions I5 and I6 are a pair of -webs I9 and 20 normal to the walls I3 and I4. Webs I9 and 20 are expanded at their tops and provided inwardly wlth opposed parallel horizontal grooves 2I and 22 and outwardly with ledge portions 23 and 24, whose toplfaccs lie in the planes of the top faces 'Ihe main elements of thev 1931, Serial No. 524,737

(Cl. Z13- 9) of web portions I'I and I8 and define the bottoms of under-cut recesses 25 and 26.

The draw bar is generally indicated by reference numeral 2l and comprises top and rear walls 28 and 29 angularly related and connected o by reinforcing Webs as at 30. The top wail, which constitutes a bitching portion, terminates laterally in ribs 3l and 32 slidably guided in grooves 2I and 22. Forwardly and centrally, wall 28 is provided with an upwardly extending 10 boss 33 provided with a vertical aperture 34. A tongue 35 has a 'bottom plate 36 secured to plate 26 of .the draw bar and provided with a recess to receive boss 33. Cast integral with plate 36 are a pair of risersv 31 and 38 which support an inte- 15 gral plate 39 in parallel relation to plate 36, plate 39 being provided with an aperture 4U registering with aperture 34.

The bumper, generally indicated at 4I, comprises a curvilinear bar 42 reinforced by longio y tudinally extending ribs and provided adjacent its ends with integral parallel flanges 43 and 44 having outwardly angularly offset ends 45 and 46 adapted to engage behind abutment portions I5 and I6. At their extremities the offset ends 25 have forwardly offset portions 45a and 46a. The bumper, hereinafter also referred to as bufferv or bufllng means, head or beam, has at least, as here shown, a central bumng plate portion projecting outwardly of the housing for the direct 30\ receptiony of buff.

In assembling the elements the draw vbar is f' first of all slid between webs I9 and 20 with ribs 3| and 32 guided in recesses 2| and 22 until its rear wall or follower plate portion 29 abuts the 35 l rear wall I3 of the bracket. Thebumper anges 43 and 44 are now introduced by a downward movement between abutment portionsf|5 and I6 and webs i9 and 20 to bring the offset portions` of the flanges behind the abutment portions of 40 the bracket, as clearly shown in Figures 1 and 5, with the flanges slidably supported on bottom wall I4. Compression springs 41 andy48 are now inserted through apertures 49 vand 50 in the bottom wall I4 of thebracket and their ends seated 45A of its offset flange portions and 45a with abutment surfaces I5a and i5b respectively, and through abutment of its offset flange portions 46 and 46a with abutment portions i6a and i6b respectively. l

Outward movement of the draw bar is limited through engagement of the front edge of its top wall 28 with the inner upper margins of the bumper and inward movement of the bumper is limited by abutment of the same parts, by abutment of offset flange portions 45 and 46 with the rear wall i3 of the bracket, and also by abutment of portions 55 and 56 with the outer edges of webs I9 and 20, the forward edges of the webs proper being set back somewhat from the forward extremities of their upper guide portions, as indicated in Figure 3.

It will thus be evident that springs 41 and 48 are 'compressed to absorb the shock of draft forces exerted on the draw bar and also to absorb the shock of impact forces exerted on the bumper, the springs being compressed in each instance.

To complete the structure and prevent the bumper from riding upwardly, top or cover plates 51 and 58 are secured to the top surfaces of web portions I1 and i8. the plates having bevelled marginal portions 51a and 58a overlying ledges 23 and 24 and engaged in recesses 26 and 26.

It will be seen that the housing together with the draft and buffer devices is entirely self-contained, the housing, more specifically, constituting an end sill so that a very simple and compact arrangement is afforded. Draft is transmitted from the drawA bar through the springs and buffer beam to the end sill through the strong transmission means constituted by the abutment provisions between the end portions of the buffer beam and the end sill. The buffer element under buff may move bodily rearwardly, or may pivot about either of the abutment surfaces |5a and I5b as fulcra.

According to Figure 6, the end sill bracket 60 is constituted by a channel bar having angle clips 6i and 62, for attachment purposes, secured to its rear face adjacent its ends. The

draw bar is constituted by a channel 63 nested within channel centrally thereof in the manner shown in Figure 7, and having secured to its top web 64 a forwardly extending plate 65 having a vertical aperture 66. A tongue 61, also secured to web 64, comprises a plate 68 above and parallel to plate 65, and provided with an aperture 69 registering with aperture 66. The top web of channel 60 has a centrally cutout portion to receive the rear end of the tongue so as to permit the rear face of channel 63 to abut the front face of channel 60.

The bumper is constituted by a curvilinear channel 10.

Passed through aligned apertures in channels 60, 63 and 10 are a pair of bolts 1I and 12 whose heads 13 and 14 are engaged in countersinks in bar, as shown in Figure 6. A bottom plate 65 is secured to the lower web of channel 80.

From the above description it will be evident that springs 15 and 16 are compressible to absorb both draft and impact shocks, draft forces being transmitted to the bracket through the draw bar,

the springs, the bumper and the bolts, and impact forces being transmitted to the bracket directly by the springs in substantially the same manner as in the embodiment first described.

In both of the described embodiments, draft is applied to the draft members in a plane above the plane of the springs and, consequently, under draft these members tend to tip forwardly and downwardly. In the -first embodiment, such stresses are taken by the guide groove flanges. In the second embodiment, these stresses are taken by the buffer member 10 on which the horizontal hitching portion 65 is adapted to ride and to be directly guided, the buffer member in turn being securely held up by plate 65.
